New ideas are often born from connecting the dots. What new ideas have emerged among the two highly trending research topics of sustainability and social media? In this study, we present an empirical analysis of 762 published works that included the terms “sustainability” and “social media” in their abstracts. The bibliographic data, including abstracts, were collected from the Scopus database. In order to conduct the analysis, we used the Latent Dirichlet Allocation (LDA), an unsupervised machine learning algorithm to extract the latent topics from the large quantity of research abstracts without any manual adjustment. The 10 main topics identified from our analysis revealed topographical maps of research in the field. By measuring the variation of topic distributions over time, we identified hot topics (research trends that are becoming increasingly popular over time) and cold topics. Sustainable consumer behavior, Sustainable community and Sustainable tourism were identified as being hot topics, while Education for sustainability was identified as the only cold topic. By identifying current trends in social media and sustainability research, our findings lay a platform from which further studies may abound.

Background: Since the latter part of the 20th Century, countries have been particularly challenged by the trade-off that exists between delivering generous welfare provisions and strong economic growth. Such dynamics have stimulated a need to better understand the causes of income inequality so as to better formulate policies that foster inclusive growth and reduce growing concerns surrounding income inequality. Method: Given its ability to succinctly summarize, analyze, and synthesize an extant body of literature from a certain genre of scholastic endeavor, this study utilizes a literature review as its proposed methodological approach. Results: From our assessment of the literature, we identified four key areas that contribute significantly to income inequality in both advanced and developing economies, these include: (i) pursuing skill-biased technological change; (ii) enhancing education systems; (iii) consolidation of globalization; and (iv) reform of the labor market and its relevant institutions. Conclusion: There is no silver bullet to achieving inclusive growth. Any policy manifesto must seek to offer a coordinated policy platform that looks to deal directly with the causes of inequality. In order to do so, consideration should be given to a range of policy areas including fiscal, education, trade liberalization, and labor market reforms.

The age of Southeast Asian developing countries’ populations is still younger than that of other regions around the world. However, recent statistics show that the tide is now turning in this regard, with many of these populations beginning to age at rates much faster than many other countries. Such developments require immediate policy action in order to create a sustainable path towards economic growth before demographic changes become less benign in the medium term. In this study, we discuss the economic consequences of population aging, increases in the economic support ratio, and a declining potential growth rate. We argue that it is essential for Southeast Asian developing countries to raise total factor productivity (TFP) growth rates so as to achieve more sustainable economic outcomes. By conducting panel regressions using data from 82 countries across the 1996–2019 study period, our study shows that increasing research and development (R&D) spending and the facilitation of structural changes that transform the digital economy landscape are key policy options that promote TFP growth.
